Biodiesel generation utilizes several different processes and technologies, each focusing to convert raw materials like vegetable oils, animal fats, or recycled greases into a sustainable fuel. The most widely used method is transesterification, where the triglycerides in the feedstock react with an alcohol, typically methanol or ethanol, in the pr

PbSe quantum dot solar cells represent a promising avenue for reaching high photovoltaic efficiency. These devices leverage the unique optoelectronic properties of PbSe nanostructures, which exhibit size-tunable bandgaps and exceptional light absorption in the solar spectrum. By carefully tuning the size and composition of the PbSe crystals, resear
